Rendering a VEG as a file slow?

I'm rendering a 3 minute piece that has some effects (levels, color correction, and glow to be specific). I wanted the entire piece to be cropped to 1:85:1 via pan/crop but the flash transitions ignore the crop and make the entire screen white.

Pre-Vegas 6 I'd render out a DV-AVI then crop THAT and render to MPG2. Another step, I know- but the only way I could make sure the flash transition wouldn't cover the entire screen outside my crop.

Anyway I figure Vegas 6 will be perfect for this. I can skip rendering it to DV-AVI first and simply drop the VEG file on another timeline as a file and crop THAT. This way I only have to do a single render.

Problem! The render is taking astronomically long. A 3 minute piece which usually might take 20 minutes (due to all the effects) is now taking 80-90 minutes?! Why is this? Is it a known issue that rendering an edit within a encapsolated VEG file on the timeline is slower than rendering the original timeline?

Are you ising V6a or V6b? V6b had some changes specifically related to the way nested vegs worked (primarily related to Preview rather than rendering I think... but maybe not)

Glen, do you have a lot of composites, or 3D tracks in your nested veg? I've found that this can really drop a nest to its knees.

My take on this, Glen, is that I presently "view" all my bits of a project in an Ensemble of nests. Once I'm fine with the Look 'n Feel of the Piece, Section, Video I then render all the bits from the other veggettes and create a spearate ASSEMBLY veg. This I then render out to AVI.

I too use a lot of Comp work, Fxs and TM manip. All this by itself is CPU intensive. Having this "attemtped" from within a Veg that has nests is a major pull on my CPU. Hey, just because sometimes we CAN do something, may not be the same as it being USEFUL in terms of time/workflow - at the present time.

Glen, think of it lke this - IMO, Sony have positioned Vegas very well for the dual core and the other F A S T options that will be winging there way to us. Vegas? Ho! It is gonna fly . . Nested Veggies are going to be amazing to work with . . .

Why not use the Zenote letterbox plug-in but inserted on the preview window?

This will place cropped bars over everything and solve the visible flash transition problem.

However it is fair to say the render time is impacted by the plug-in but nowhere near as severe as you have encountered.

Not a lot of composites really...just 2 video tracks, one for the video and one for the vignette (Vegas Gradient, Oval- Black to Transparent).

I know this gradient layer sludges things up but it seems 10 fold in a nest. I tried rendering the original timeline out and I was getting an estimated time of 30 minutes. The same timeline rendered as a nest took 90 minutes.

I was just curious if this was a known phenomenon.
